  In the above configuration, the operation unit TP is configured by a touch panel or the like on the front surface (front surface) of the drive recorder DR as described above, and receives an operation by the user and outputs an operation signal corresponding to the operation to the control unit 1. To do. The display unit DP displays information to be presented to the user as a function of the drive recorder DR under the control of the control unit 1 using, for example, an image or an icon. Next, the measurement unit 11 detects the current position, speed, or traveling direction of the vehicle to which the drive recorder DR is attached, for example, using GPS (Global Positioning System) or autonomously, and controls each detection result. Output to part 1. Next, under the control of the control unit 1, the microphone MC collects, for example, in-car sound or sound of the vehicle to which the drive recorder DR is attached, and outputs the detection result to the control unit 1. At this time, the microphone MC may collect sound or sound outside the vehicle. On the other hand, the event detection unit 12 uses an acceleration sensor (not shown) to apply an impact greater than a preset value to the drive recorder DR (and thus the vehicle to which the drive recorder DR is attached), sudden acceleration or sudden deceleration or sudden steering in the vehicle. The occurrence of the above event and the occurrence state thereof are detected, and the detection result is output to the control unit 1. Finally, the recording unit R is configured by a non-volatile memory such as an SSD (Solid State Drive). Then, in addition to controlling the operation as the drive recorder DR described above, the control unit 1 executes a recording process according to the embodiment described in detail with reference to FIGS. The recording of the video data picked up by the camera C and the sound data collected by the microphone MC at the timing when the event is detected is controlled. The imaging data stored in the recording unit R is used for, for example, post verification of an accident or the like.

  Next, the recording process according to the embodiment, which is executed in the drive recorder DR according to the embodiment having the above-described configuration, will be described collectively with reference to FIGS. 5 and 6.

  In the recording processing according to the embodiment, the power switch (not shown) is turned on after the attachment of the drive recorder DR to the room mirror RM is completed according to the mode shown in FIGS. 2 and 3, and the power is supplied from the power supply unit. Then it starts. The power supply from the vehicle battery or the like is turned on when the ACC (Accessory) switch of the vehicle to which the drive recorder DR is attached without turning on the power switch as the drive recorder DR itself and the power supply unit. The recording process according to the embodiment may be started by starting the above. Then, as shown in FIG. 5, when the recording process according to the embodiment is started, the control unit 1 acquires video data and audio data continuously output from the camera C and the microphone MC, respectively (steps). S1). Further, the control unit 1 turns on an acceleration sensor (not shown) in the event detection unit 12 in parallel with the processing of step S1. Then, the control unit 1 records the video data and the audio data that are continuously acquired in one file, which is a recording management unit (ie, recording unit) when recording the recording unit R along the time series. The timing of the corresponding preset recording time is started by a timer (not shown), and the name of the file including the video data and audio data acquired at that time (see step S1) is defined, and the video data Recording of the audio data to the recording unit R is started (step S2). In the following description, a preset recording time corresponding to one file is referred to as “file recording time”. An example of the file recording time is 1 minute. In step S2, the control unit 1 records information such as the time, the position of the vehicle to which the drive recorder DR is attached, the traveling speed, and the traveling direction in association with the time, together with the video data and the audio data. Record in part R.

  Next, the control unit 1 determines whether or not occurrence of an event is detected by the event detection unit 12 (step S3). When the occurrence of any event is not detected in the determination in step S3 (step S3: NO), the control unit 1 proceeds to determination in step S5 described later. On the other hand, when occurrence of any event is detected in the determination in step S3 (step S3: YES), the control unit 1 next acquires event information corresponding to the event in which the occurrence is detected from the event detection unit 12. Then, it is recorded in the recording unit R in association with the video data and the audio data recorded at the occurrence of the event and in parallel with the video data and the audio data (step S4). At this time, the event information includes type information indicating the type of the event (that is, any one of the shock, the sudden acceleration, the sudden deceleration, the sudden handle, etc.), time information indicating the occurrence time of the event, and The event includes acceleration information indicating the magnitude and direction of the acceleration detected by the acceleration sensor.

  Next, the control unit 1 determines whether or not the ACC switch has been turned off (step S5). When the ACC switch is turned off in the determination in step S5 (step S5: YES), the control unit 1 next performs the above event until the ACC switch is turned off after the start of timing in step S2. It is determined whether or not occurrence has been detected (step S12). If an event has occurred in the determination in step S12 until it is turned off (step S12: YES), the controller 1 determines whether or not the file recording time has elapsed at that time. The video data and audio data recorded until the time of turning off is paired to generate one file, and the file name indicating the file (see step S2 above) and the event corresponding to the generated event The event information (see step S4) is recorded in the recording unit R (step S14). Then, the control unit 1 integrates the video data and audio data for each file recorded so far together with the video data and the audio data, together with the off process set in advance in the recording process according to the embodiment. One file (step S15). Thereafter, the control unit 1 ends the recording process according to the embodiment.

  On the other hand, if no event has occurred until the ACC switch is turned off in the determination in step S12 (step S12: NO), the control unit 1 starts measuring the file recording time (step S2 above). The audio data recorded until it is turned off after reference is erased from the recording unit R (step S13). Thereafter, the control unit 1 proceeds to step S14 and executes the above-described processing using video data other than the erased audio data.

  On the other hand, when the ACC switch is not turned off in the determination in step S5 (step S5: NO), the control unit 1 next determines whether or not the file recording time has elapsed since the start of time measurement in step S2. Determination is made (step S6). If it is determined in step S6 that the file recording time has not elapsed (step S6: NO), the control unit 1 returns to step S3 and repeats the processes in steps S3 to S5 described above.

  Next, in the determination in step S6, when the file recording time has elapsed (step S6: YES), the control unit 1 sets one video file and audio data recorded at the file recording time as a pair. Generate. Then, the control unit 1 sets the generated file to the event information corresponding to the generated event only when the file name indicating the file (see step S2) and the determination in step S3 is “YES”. At the same time, the data is recorded in the recording unit R (see step S7).

  Next, the control unit 1 determines whether any event has occurred during the file recording time for the file recording time determined to have elapsed in step S6 (step S8). If any event has occurred in the determination in step S8 (step S8: YES), the control unit 1 is included in the file recorded first after step S7 (that is, the file recorded immediately after). (For example, setting a flag indicating that the audio data is not deleted) is set (step S10). Thereafter, the control unit 1 returns to step S2 and performs recording processing of video data or the like corresponding to the next file recording time.

  On the other hand, if no event has occurred in the determination in step S8 (step S8: NO), then the control unit 1 determines whether there is a file recorded immediately before the latest file recorded in step S7. It is determined whether or not (step S9). In the following description, the file recorded immediately before the latest file recorded in step S7 is referred to as “immediate file”. If it is determined in step S9 that there is a previous file (step S9: YES), the control unit 1 deletes the audio data recorded together with the corresponding video data in the previous file from the recording unit R (step S11). Thereafter, the control unit 1 returns to step S2 and performs recording processing such as video data corresponding to the next file recording time. On the other hand, if there is no previous file in the determination in step S9 (step S9: NO), the file recorded in the previous step S7 is the first file after the start of acquisition of video data or the like (see step S1 above). Therefore, the control unit 1 returns to step S2 as it is, and performs recording processing of video data and the like corresponding to the next file recording time.

  Next, a recording mode of each file and the like obtained as a result of executing the recording process according to the embodiment described with reference to FIG. 5 will be described with reference to FIG. FIG. 6 shows a case in which the file recording time according to the embodiment is 1 minute (60 seconds), the vehicle is started at 10:10:00, and the vehicle is stopped at 10: 5: 30. Illustrated. In FIG. 6, the range of video data and audio data corresponding to one file is indicated by a one-dot chain line.

  In the drive recorder DR according to the embodiment, when the power switch is turned on as described above or the ACC switch is turned on, the video data acquired from the camera C and the microphone MC as described above. And the audio data and the time, the position of the vehicle to which the drive recorder DR is attached, the traveling speed, the traveling direction, and the like are recorded in the recording unit R in correspondence with the time (that is, synchronized in real time). (See step S2 in FIG. 5). At this time, video data, audio data, and the like are recorded as separate files each time the file recording time elapses (see step S7 and step S14 in FIG. 5). In the case illustrated in FIG. 6, the file name of each file corresponding to the file recording time of 1 minute indicates the start timing of the file recording time corresponding to each, and “201610191001” → “201610191002” → "201610191003", ... (see the upper figure of Fig. 6). In addition, video data included in each file is video data VD1 or the like, and audio data is also audio data AD2 or the like.

  For example, no event is detected by the event detection unit 12 until the recording of the file whose file name is “201610191002” (including video data VD2 and audio data AD2) in the recording unit R is completed. In this case (see step S8 in FIG. 5: NO), after the recording of the file with the file name “201610191002” is completed (see step S7 in FIG. 7), it was included in the file immediately before that from the file with the file name “201610191001”. The audio data is deleted (see step S11 in FIG. 5).

  For example, when any event is detected by the event detection unit 12 before the recording of the file having the file name “201610191003” (including the video data VD3 and the audio data AD3) to the recording unit R is completed. (See step S3 in FIG. 5: YES), the timing at which the occurrence of the event is detected for the video data VD3 or the like being recorded included in the file “201610191003” (in the example shown in FIG. At time 3: 3: 20, an index indicating the type of the event that occurred is added as the event information and recorded in the recording unit R (see step S4 in FIG. 5), and at the timing when the occurrence of the event is detected. The file with the corresponding file name “201610191003” and the file name “201610191004” recorded (recorded) in the recording unit R before and after that file And from a file of the file name "201610191002", the audio data AD2 corresponding to each controlled so as not to erase audio data AD3 and audio data AD4 (Figure 5 Step S9: refer to NO and the step S10).

  On the other hand, for example, when the power supply to the drive recorder DR is stopped before the recording of the file having the file name “201610191005” to the recording unit R is completed (see step S5: YES in FIG. 5), recording is performed at that timing. If recording to the part R is stopped but no event is detected during the recording of the file before the recording is stopped (see step S12: NO in FIG. 5), the audio included in the file name “201610191005” Data is deleted (step S13 in FIG. 5). Then, along with the above-described off processing, the video data VD2 and the audio data AD2 etc. for each file recorded so far are integrated for each video data VD2 and the audio data AD2, and one video data VDa and The audio data ADa (see the downward white arrow in FIG. 6) is recorded in the recording unit R as one file including the video data VDa and the audio data ADa (see the lower diagram in FIG. 6 and step S15 in FIG. 5). At this time, the new file name after the integration is, for example, “201610191001-201610191005” as illustrated in the lower diagram of FIG.

  As described above, according to the recording process according to the embodiment, after recording the video data and the audio data from the camera C and the microphone MC, the recorded audio data includes at least the audio data related to the event. Since a part of the recorded audio data remains in the recording unit R, desired video data and audio data can be recorded, and necessary audio data can be stored in the recording unit R while paying attention to privacy protection. Can leave. In this case, only audio data related to the event may be left in the recording unit R in order to further ensure privacy protection.

  In addition, the audio data related to the event is audio data corresponding to the sound collected within a predetermined time including the event occurrence time (in the case of FIG. 6, three minutes including the preceding and following files). Therefore, necessary audio data can be reliably left in relation to the event that has occurred.

  Furthermore, when recording video data and audio data, respectively, the continuous video data and audio data are recorded separately in time-sequential files on each recording (see FIG. 6). Video data and audio data can be reliably recorded.

  Furthermore, since a plurality of files including audio data related to the event are integrated and audio data corresponding to the integrated file is left in the recording unit R (see the lower diagram in FIG. 6), the configuration for recording management is simplified. Therefore, necessary audio data can be reliably left in the recording unit R.

  As described above, the recording unit R according to the embodiment may be configured to be removable from the drive recorder DR as, for example, a card-type recording medium in addition to those built in the drive recorder DR.

[Modification]
Next, a modified example corresponding to the above-described embodiment will be described with reference to FIG. FIG. 7 is a block diagram showing a detailed configuration of the recording system according to the modification. In FIG. 7, the same member numbers as those of the constituent members in the information recording apparatus S are used for the constituent members of the examples corresponding to the constituent members in the information recording apparatus S according to the embodiment shown in FIG. Yes.

  In the above-described example, the case where the drive recorder DR according to the information recording apparatus S according to the embodiment is mounted in the vehicle has been described. However, in addition to this, the vehicle and the server device fixedly installed are connected to the Internet. The information recording apparatus S according to the embodiment can also be applied to a recording system connected via a network such as the above.

  That is, as shown in FIG. 7, the recording system SS according to the modified example includes a drive recorder DR1 according to the modified example attached to a vehicle and a server device SV that is fixedly installed via a network NW such as the Internet. It is configured by wireless connection.

  The drive recorder DR1 includes a transmission unit 20, a CPU, and a ROM in addition to the measurement unit 11, the event detection unit 12, the camera C, the microphone MC, the operation unit TP, and the display unit DP similar to the drive recorder DR according to the embodiment. And a control unit 21 including a RAM and the like. On the other hand, the server device SV includes a recording unit R similar to the recording unit R according to the embodiment, a map database 20 that includes SSD or HDD (Hard Disc Drive) and the like and records map data, and a display unit that includes a liquid crystal display or the like. 21, a receiving unit 22, and a control unit 1 similar to the control unit 1 according to the embodiment. And as shown with a broken line in FIG. 7, the control part 1 of the server apparatus SV comprises an example of the information recording device S which concerns on embodiment.

  In the above configuration, the control unit 21 of the drive recorder DR1 according to the modified example has the video data acquired from the camera C and the microphone MC when the power switch is turned on or the ACC switch is turned on. The audio data and the time, the position of the vehicle to which the drive recorder DR1 is attached, the traveling speed, the traveling direction, and the like are associated with the time in real time to the server device SV via the transmission unit 20 and the network NW. Send. When the event detection unit 12 detects any event, the control unit 21 transmits an index indicating the type of the generated event as the event information to the server device SV via the transmission unit 20 and the network NW.

  On the other hand, the control unit 1 of the server device SV receives the network NW and the receiving unit from the information such as the position of the vehicle sequentially transmitted from the drive recorder DR1 attached to the vehicle and the event information transmitted when the event occurs. 22 is received. Thereafter, the control unit 1 executes a recording process similar to the recording process according to the embodiment described with reference to FIG. 5 based on the received information such as the position and the event information, and records each file in the recording unit R. To do. At this time, the control unit 1 controls the map data corresponding to the position indicated by the received position information to be read from the map database 20 and recorded in the recording unit R in association with the recorded file. As a result, in the recording unit R of the server device SV, the integrated video data VDa and audio data ADa are recorded for each drive recorder DR1 (that is, for each vehicle) in the recording mode described with reference to FIG. It will be. The recorded video data VDa, audio data ADa, and the like are subjected to processing such as displaying them on the display unit 21.

  As described above, according to the recording process according to the modified example, in addition to the effects of the recording process according to the embodiment, in addition to the audio data related to the event, the video data corresponding to the audio data is stored in the server device SV. Since the recording unit R is left outside the vehicle and is provided outside the vehicle, the desired video data VDa and audio data ADa can be stored in the recording unit R even if an accident or the like occurs in the vehicle itself. Can be recorded and left.

  In addition, since the server device SV including the recording unit R is fixedly installed outside the vehicle and acquires (receives) the video data, the audio data, and the event information from the vehicle, the desired video data in relation to the event information. VDa and related audio data ADa can be reliably recorded and left.

  As another modification, for example, after recording video data and audio data respectively acquired from the camera C and the microphone MC in the recording unit R built in the drive recorder DR, the audio data recorded in the recording unit R is recorded. Alternatively, a part of the audio data related to the event or only the audio data related to the event may be left on a recording medium such as a card by copying or moving from the recording unit R. At this time, all the video data recorded in the recording unit R may be copied or moved to the other recording medium. In the other modified examples as described above, the recording unit R corresponds to an example of the “second recording unit” according to the present application, and the other recording medium corresponds to an example of the recording unit R according to the embodiment.
